Description

Technical Field

[0001] The utility model relates to the technical field of police on-site investigation equipment, in particular to a search and investigation device. Background Art

[0002] On-site investigation usually refers to an investigative measure carried out by investigators after a criminal case or traffic accident occurs, in order to collect evidence, ascertain the truth, determine the nature of the case and the attribution of responsibility. On-site investigation is an important part of criminal proceedings or traffic accident handling, which helps to provide key clues and evidence for the investigation, prosecution, trial or determination of accident responsibility. It usually requires taking photos, videos, and various trace evidence, such as fingerprints and footprints.

[0003] In the existing technology, field investigation work often involves the coordinated use of multiple devices, such as fingerprint collectors, cameras, light sources, etc. These devices are usually large in size and heavy in weight, which is not only inconvenient to carry, but also complicated to operate during field investigation, affecting the efficiency of investigation. At the same time, the functions of traditional equipment are relatively single, lacking integration and diversity, and it is difficult to meet the actual needs of field investigation work. Therefore, it is of great significance to develop an investigation device that integrates commonly used field investigation equipment, has a small size, light weight, and optimized functions, in order to improve the efficiency of investigation and the quality of case handling.

The display system uses a high-resolution display screen 201, which can display the captured images and inspection data in real time, facilitating the inspectors to keep track of the inspection progress at any time. The shooting component 4 uses a high-definition camera, which, in combination with a lens adjuster, can meet the shooting requirements at different angles and distances. The shooting light source can provide multiple light source modes to adapt to the lighting needs of different inspection environments. In terms of function optimization, this device has been comprehensively upgraded on the basis of traditional devices. For example, the shooting component 4 supports high-definition video shooting and real-time transmission, facilitating remote guidance and collaboration; the display screen 201 has a touch function, enabling convenient operation and parameter setting. By integrating multiple inspection devices into one, this device simplifies the process of carrying and using by inspectors, improves work efficiency, and has a high degree of integration;

[0036] Among them, the fingerprint test kit 6 adopts an electric ultra-fine atomization technology and a targeted fluorescence ultra-fast visualization technology. Its principle is to atomize the biological composite fluorescent reagent into ultra-fine particles and uniformly attach them to the biological traces on the physical evidence. After being irradiated by an excitation light source, a focusing-induced luminescence phenomenon occurs, thereby visualizing and positioning difficult biological traces. It can non-destructively visualize the potential biological traces on the physical evidence objects at the scene, such as: fingerprint traces, trace exfoliates from human contact, human body fluid stain traces and other biological physical evidences. It can quickly visualize the biological traces on non-permeable objects, relatively fresh biological traces on permeable objects, and contact traces on permeable objects. It has a super strong physical adsorption ability, does not damage the biological DNA of the test material, and can ensure the authenticity, integrity and biological activity of the original information of the physical evidence. After the physical adsorption treatment of the reagent, it does not affect any secondary treatment;

[0037] The reflection light source mirror group 5 can be used to capture the fine features of fingerprints or dust and convert them into digital signals for the staff to use. It adopts the well-known technology of those skilled in the art, so no more description will be given here.
